Soybeans harvested as forage are high in protein and lower in fiber than grasses.

Long before soybeans were cultivated as oil seed crops, they were first domesticated and used in the United States primarily as a forage. Soybeans harvested as forage are high in protein and lower in fiber than grasses making them an excellent forage if harvested and stored properly. Soybeans harvested as a forage can have dry matter yields as high as 5 tons per acre but are often much lower when the soybeans are planted late as a rescue forage or transitioned to forage due to drought.

Soybean feed value from Hintz et.al. from the late 1980’s showed that when soybeans were harvested at R7, crude protein values across 3 different varieties ranged from 18.1-20.5%. The NDF values for the soybeans ranged from 39.5-42.2. Dry matter yield ranged from 3-3.6 tons per acre. Row spacing and seeding rate had little effect on yield or forage quality. However, harvest timing affected all factors. When harvested at Continue reading Using Drought Stressed Soybeans for Hay or Silage →

Forage Nitrate Toxicity a Major Concern as Drought Worsens

Weather conditions across Ohio have been challenging this growing season with some areas of the state reaching a D3 drought status. Other areas of the state may not currently be under drought status but are drier than normal and at risk of quickly experiencing a flash drought. These adverse growing conditions can cause unforeseen challenges with forages. We have had multiple reports of high nitrate levels this year in early harvested summer annual forages as producers needed feed.

Plants readily take up nitrates from the soil, even under dry or cool conditions.  Once in the plant, nitrate is converted to nitrite, then ammonia, and finally into amino acids and plant protein. Any environmental stress that significantly slows down plant photosynthesis and metabolism can lead to excessive nitrate levels in the plant because the nitrate uptake from the soil will be faster than its metabolism into plant protein. Such stresses include drought, frost, extended cold weather, cloudy conditions, or hail damage. While Continue reading Forage Nitrate Toxicity a Major Concern as Drought Worsens →

Managing Forage to Finish 2024

Christine Gelley, OSU Extension Educator ANR, Noble County

With the drought conditions we have experienced this summer, many livestock producers and haymakers are concerned about the winter to come and how to stretch resources to next spring when the supply of stored forages will be low. Other than doing the rain dance and hoping for yield salvation on third cutting hay, what else can we do to boost forage availability now and through to the spring?

We can practice good management tactics. Those ones that we should be doing every year, but become more critical during times of stress, like now. We can restrict animals from overgrazing areas that we will need later this fall. We can consider reducing the size of the herd while prices are decent at the sale barn and have fewer mouths to feed through the winter. We can start shopping for supplemental winter feed now, because as supply dwindles and the months turn cold, demand will increase and so will costs.

There is limited time left to plant emergency annual forage crops, but it is an option. If we get Continue reading Managing Forage to Finish 2024 →

How to Meet the Mineral Needs of Livestock in Mixed Pastures

Minerals are critically important for the health and well-being of livestock. Reproductive performance and growth are improved when animals consume proper amounts of minerals (and vitamins). Animals have specific requirements for these minerals and differ by species and level of production.

One problem many have is that cattle, sheep and goats are frequently pastured together. Since sheep are vulnerable to copper toxicity, a general livestock mineral mix without copper is usually fed to the group. But that leaves cattle and goats without proper copper in their diets. This article provides alternatives for supplementing different livestock.

Sheep options
Purchase or construct a small-area mineral feeding station that larger animals can’t access. One option is Continue reading How to Meet the Mineral Needs of Livestock in Mixed Pastures →

How to Sample Hay

With the recent drought Ohio and much of the United States has experienced this year to date, analyzing and understanding forage quality will be critical for operation success. Wether you are feeding a few sheep in your back yard or have 1,ooo ewes indoors, knowing what you are providing to your stock in your pastures or in the feed bunks is important. This week, Mindy Ward outlines key steps to follow when collecting a hay sample.

As hay condition comes into question, take a closer look at your harvested bales.

Ewe Flock Nutrition

Introduction
Nutritional management is one of the most important aspects of sheep production. Ewes that are fed appropriately are more fertile, milk better and wean more lambs that grow faster (Figure 1).

Not only do well-fed ewes wean more pounds of lamb per year, but they are healthier and more resistant to disease than ewes that are under nutritional stress. In fact, many production challenges for sheep producers are caused by inadequate nutrition, rather than disease.

Additionally, feed costs are the single largest expense on sheep farms in Ontario, accounting for approximately 41% of total expenses. The 2010 Ontario Sheep Enterprise Analysis Summary (26 producers, representing 10% of the provincial flock) reported average feed costs of $106.70 per lamb produced for the 10 least profitable flocks and $69.00 per lamb (35% less) for the 10 most profitable flocks.

Appropriate feed management can be the difference between a profit or a loss for each lamb sold. Therefore, it is imperative that producers evaluate the feed resources they have and manage them carefully to maintain good ewe nutrition and the profitability of the flock.

How to Take Hay Samples

Get into the routine of sampling after every cutting. Here are tips for how to access a probe and how to take proper samples.

“I know my hay” is a common reason folks give for why they do not sample their hay. However, environmental factors can alter nutrient levels and create a scenario where what you think you have and what you do have for hay do not match.

A solid habit to form is sampling hay after each cutting, according to Nick Minton, beef systems specialist at Purdue. He echoes the sentiment that nobody can know the nutrient levels of their hay without testing.

“The most-skilled producer will look at a hayfield and say, Continue reading How to Take Hay Samples →

Forage Maturity Across Ohio

Jason Hartschuh, Dairy Management and Precision Livestock, Field Specialist

Warm weather this spring especially over the last couple of weeks has rapidly progressed forage maturity. Harvesting forages at the proper time for the livestock you are feeding is critical to farm profitability. Poor quality forages must be supplemented to maintain livestock. In the southern part of the state, many forage grasses are in head while in the northern part of the state, some varieties of Orchard grass and barnyard grass are in head but most are still in the vegetative stage but will be in head within a week.

Many growers may base harvest decisions primarily on alfalfa maturity; however, this method can be misleading due to climatic variations affecting the rate of bud and flower development.

Spring changes of alfalfa %NDF can increase about 5 percentage units each week. Therefore, it is imperative for growers to be monitoring their Continue reading Forage Maturity Across Ohio →

Use a Grazing Stick to Measure Forages

Sticks help determine an estimate of available forage dry matter per grazing paddock.

Measuring the amount of forage available for livestock to graze is a helpful task for designing and adjusting pasture rotations for grazing livestock.

There are many potential methods for measuring the amount of forage mass growing in a pasture. All of them require time spent in the pasture and repetitious measurements to develop estimations of whole pasture forage availability.

One of the simplest methods for estimating forage availability is using a grazing stick.

What does the grazing stick do?
A grazing stick combines information about forage height, forage density, species of forages growing in the pasture and residual grazing heights into a tool that looks like a yardstick. Continue reading Use a Grazing Stick to Measure Forages →
